Reiser R demonstrated that the high levels of saturated fatty acids in ruminantanimal fat are due to the hydrogenation of the dietary unsaturated fatty acidsin the rumen ().

Isovaleric acid is clear colorless liquid that is sparingly soluble in water, but well soluble in most common organic solvents.; It has been suggested that isovaleric acid from pilot whales, a species frequently consumed in the Faroe Islands, may be the unusual dietary factor in prolonged gestation in the population of the Faroe Islands.; Previous studies suggested that was due to the high intake of n-3 polyunsaturated fatty acids has been, but fatty acid data for eicosapentaenoic acid (EPA) and docosahexanoic acid (DHA) in blood lipids of Faroese and Norwegians was reviewed in terms of the type of fish eaten (mostly lean white fish with DHA much greater than EPA); the popular lean fish, thus, probably provides too little EPA to produce a marked effect on human biochemistry.
